A slope adjustable head for an adjustable pedestal (10) for supporting beams, panel members, typically pavers, in accurate edge aligned relation, in a level plane is disclosed. The pedestal (10) includes a base block (12) and a series of inter-engaging threaded annular elements (20, 30) which can be rotated relative to each other to adjust the height of the top of the pedestal in a screw jack fashion. A slope compensator is located at the top of the pedestal and comprises a slope compensation plate (100) and a head member (50). Rotation of the slope compensation plate (100) about its center of curvature causes the angle of the adjustment plate relative to the vertical axis to change thus allowing for compensation for the slope of the surface on which the pedestal is standing.

The invention claimed is: 1. An adjustable pedestal adapted to support panel members of an elevated floor structure comprising:a height adjustable support structure including a base and a head assembly, the base defining a plane on which the support structure stands in use, said head assembly including:a head member; anda slope adjustment plate, wherein the head member defines a first part-spherical, surface having a first radius of curvature, and the slope adjustment plate has a first face defining a planar area and an opposite face defining a second part-spherical, surface having substantially the same radius of curvature as the first surface, and wherein the second part spherical surface may be supported on the first part spherical surface, with relative movement of the second part-spherical surface on the first part-spherical surface adjusting the angle of the planar portion of the adjustment plate relative to the plane of the base, wherein the slope adjustment plate defines at least one depending peg and the head member defines an array of holes for receiving the peg and which extend about the center of the top surface of the head member for fixing the slope adjustment plate relative to the head member in two or more different relative orientations.
